To all weer?, t man] concern.'

Be it known that I, Josnr Knorr, a subject` ot' the King oi Austria, anda resident of Bloomiield, in the county of Esser; and State oi NewJersey, have invented new and usetul Improvements in Motorcycles and thelike, otwhich the following is a speciiica tion.

The objects of this invention are to provide an. improved windshield formotorcycles; to secure a lirm and stable mounting ot the same uponthe'steering post and liandle bars; tocombine with a windshield a topwhich shall cover and protect the rider; to allow suitable motionbetween said top andwindshield, to accommodate steering the motorcycle;to mount the top iirmly and iixhedlyupon the trame of the motorcycle;toy secure an improved construction ottop; to provide suitable means torholding the top both in raised or open position and in lowered lorclosed position; to provide lower lateral shields at the iront of themachine which coperate with Athe windshield and top to protect therider; to provide inside the windshield a suitable instrument board, andto secure other advantages and results as may be brought out. in thefollowing description.

Referring to the accompanying drawings in which like numerals oireierence indicate the same parts throughout the -several views,

Figure l is a side elevation of a motorcycle illustrating my invention,the side of the top being shown uniastened and partly lifted, forgreater clearness;

Fig. Q is a similar elevation with the top and windshield in verticalcentra-l longitudinal sectionv and the lower lateral shield next theobserver broken away;

Fig. 3 is a transverse sectional view of the motorcycle and top, takenjust back of the handle bars and in front of the drivers seat and themotor looking toward the front of the machine;

Fig. fl is a similar section taken just back of the drivers seat andlooking toward the rear of the machine;

Fig. 5 is a detail perspective of the pivotal connection between the`windshield and top; Y

Fig. 6 is a perspective view of the instrument board detached;

Fig. is a perspective View of one of the lower lateral shields; 'Y Fig;8 is a perspective view oi one or' the uprights and its attached partsby means oi which the top is securedto theirame of the motorcycle; l

Fig. 91's a side view oi the frame of the top` and those portions of themotorcycle to which it is attached, showing the positions assumed by theparts of the topas it begins to close or lower, and

l0 is a `similar view illustrating the top nearly closed orloweredlv `tIn the particular embodiment of the invention illustrated in saiddrawings, l" have shown a motorcycle having a front fork-'l the stem 2of which is carried in ,an upper head fitting 3 above whichis a T oranchor plate l fast with respect to the stem 2 and the sides oi the forkl which extend at the side oit said head fitting 'up to the anchorplate. It will therefore be seen thatthe stem 2, anchor plate 4 andforli sidesA all turn together. Above said anchor plate l are splitclamps 5, 5 projecting toward the rear of the motorcycle and held inposition by bolts 6,' 6 which depend therethrough and through saidanchor plate into the ripper ends of the fork sides. In carrying out: my

invention I mount upon these same bolts 6, Y

6,A a bracket 7' having arms 8,1 8" extending upwardly and supportingawindshield 95` 'The' windshield preferably comprises a frame Il() withinthe lower part of which is fiXedly secured the lower section ll'of thewindow, and also to4 which is secured an upper sectionlt, preferablypivoted upon a horizontal line so its lower edge can swing toward andaway from the rider. As showin-'the lower portion of the'frame'lO andlower section l1 of the window are inclined nfrom their lower edgesupwardly rearward of the motorcycle, whi'lerthe upper part of the Jframe'is substantially vertical, although this may be otherwise if found moredesirable. 'In manufacture, I prefer to have a central point of theupper vedge of said frame 10 intersected by the axis from this centralpoint a pivot pin 111 is iXedly secured upon the frame to standk uprightfor purposes hereinafter described. i

As shown in the drawings, l provide braces 15 from the sides of theframe 10 downwardly rearward to the handle bars 16 of the motorcycle.These braces 15 are shown attached securely to the handle bars 16 bymeans of split collars 17 having parallel ends upon vopposite' sides ofthe lower ends of the braces through which clamping screws may be passedto secure the parts together and the collar upon the handle bars.. Itmay be here noted that the handle bars 16 do not pass over the steeringpost, but are off-settoward the rear Vof the motorcycle and are held inthe split clamps 5, 5 above described. Y

Froin the lower and preferably front edge of the frame 10 of thewindshield, depends an apron 18 which cooperates with the windowportionsabove toshield the rider, and in practice it is preferable tomake this apron 18 of sheet metal, although itvwill be obvious that anydesired material may be used. From the side edges of the apron 18gauntlet extensions 19, 19 are provided which extend rearwardly at thesides of the handle bars but spaced outward far enough therefrom so asnot to interfere with the proper control yof the handle bars by therider. These gauntlet extensions 19, 19 are shown as extendingv upwardlyto aboutthe middle of the frame 10 and secured thereto upon the outsideof the braces 15. For

i added rioidit f the lower nart of the Tauntt3 n 7 l. ID

let extensions 19, 19 are connected to the braces 15, l5 by lateralbrackets 20, 20.

Combined with the windshield for protecting the rider, is a top 21supported from afiXed part of the motorcycle. ln carrying out thisfeature of my invention, l provide uprights 22, 22 back of the seatwhich have their lower ends bent forwardly in the pres- 4 ent embodimentand secured by bolts 24: which clamp the forward part of the frame tothe leaf spring 25, although it is to be understood that other supportmay be provided for these uprights as found desirable or necessary.Between these uprights are cross-pieces 26, 27 one near the top and onelower down on said uprights, which form a chair-like back for the rider,and as shown these crosspieces arebent rearwardly between said uprights.For added protection to the rider, I have shown a skirt 28 dependingfrom the lower cross-piece 27, said skirt having a forwardly directedportion 29 from its side edges upon the Voutside of the up rights 22 towhich they are fastened.

Pivoted, as at 30, to the uprights 22, 22 preferably above the lower'cross-piece 27,

and below the upper cross-piece 26, are linksl 31 adapted to be swungwith their free ends upward and held between fixed lateral stops are theends of theupper and lower crosspieces 26, 27 respectively, offset fromthe body of the cross-pieces so as to project from the forward edge ofthe uprights.

To the free ends of the links 31 are pivot* ed ends of a bow 35, which,when the top is raised as in Figs. 'l and 2, stands upward forsupporting the back end ofthe top cove ing.36. Near the top of this rearbow, as

vviewed in raised position, are side pieces 37,

37 which extend horizontally forward from points of pivoting 38, 38 onthe rear bow 35. To the other or forward endsrof these side pieces 37,371 have shown pivoted, as at 39 the ends of a front bow llt), which, inopen or raised position of the top, are inthe same plane with said sidepieces. Upon this front bow l0, at a middle partlthereof', is providedmeans for supporting the front of the top. upon the windshield. Thismeans is shown as a bracket 4.1 secured to the bow so as to lierin theplane thereof and project from said bow in the same general direction asthe ends of the bow, which, with the top raised, is rearwardly of themotorcycle. At its rearward end,`this bracket has a vertically disposedhole for receiving the pivot pin 1e upon the top of the windshield'frame. Since this pin is upon the axis of turning of the front fork,said fork may be turned with vthe top resting upon the windshield. l v L^Both for supportingthe middle part of the covering 3G and for holdingthe side piece 37 and front bow l0 in proper relation, a middle bow 42is provided pivoted at its ends, as at `43. tothe side pieces apredetermined distance from thepivoting of said side pieces to the frontbow. '.lhis middle bow slopes upwardly forward to substantially avertical plane through said pivoting of the front bow, and pivotallyattached to said middle bow at its sides near the front thereof areprops 414 also pivotally attached to the front bow. These props areshown supported by releasable hooks l5 pivoted to the side pieces 37anc.' taking over appropriate protuberances noon props, although thismight beotherwise.

ln addition to the top cover 36, I also provide aback curtain e6 andside curtains 47, 427. These sidel curtains are provided with suitablestraps 43, 19 adjacent their bottom edges at the front and backrespectively of the curtains. The back strap 49 is adapted llO to vbepassedarcund theupright 22 adjacent the attachment thereof to the spring25, thus holding the curtain down, but it will `be understood that thisstrap `may be attached to any other tixedpart of the motorcycle iffoundmore desirable. The front strap is adapted to beiinsertedfthroughholes 50 adjacentk the outer edges of lower lateral shields supportedn'pon the front tubing 52 of the motorcycle frame, which thusl hold thecurtains spaced outward from the rider.

The lower lateral shields 5l above referred. to are preferably of sheetmetal and extend from adjacent the front apron i8 downward.substantially to the foot rest 53 affording added protection for therider. For mounting the lower lateral shields 5l. upon said front tubing52, I have shown clamps 511;, 55 near the top and bottom respectively ofthe said shields, 4said clamps leach comprising a pair of membersbetween which the said tubing may be pinched upon securing said memberstogether by bolts 56. One member of each of these clamps is carried byone of the lateral shields and the other member is carried by the othershield.

ln this way, the shields will be `clamped upon the frame of themotorcycle, but may be removed by loosening said bolts. As shown. theselateral shields also have in themselves openings 57 near the inner edgesof said shields adjacent the engine cylinders where by a draft of air isobtained for cooling the engine. Preferably flanges 58 are turned upadjacent said openings 57 along the edge thereof farthest from themotorcycle frame, so as to direct the current of air toward the engine.

lllhen it is desired to lower the top, the swinging stops 33 at the backof the uprights .22 are swung upwardly from behind the links 31 whichmay then be swung downwardly (see Figs. 8, 9 and 10). rEhe releasablehooks 4-5 are also swung out of engagement with their protuberances uponthe props JA permitting the front bow Al0 to be swung upwardly backward,thereby swinging the middle bow l2 upwardly back so that both of saidbows may close downwardly uponthe side pieces 37, 3T and all of saidparts fold down upon the rear bow 35. A suitable support 59 is providedat the back of the motorcycle for receiving the top when thus lowered,said support preferably being midway between the sides of the top. Astrap 60 is shown carried by this support 59 by means of which the topmay be securely held in place upon the said support.

lllounted upon the handle bars, preferably just inside ofthe windshield,is an instrument board 6l upon which any desired instruments may bemounted for the information and convenience of the driver. Thisinstrument board is shown as sloping rearwardly downward and is carriedby means of metal straps 62, at its ends which are bent aroundthelhandle bars and clam ped by means of screws.

l@bidonsly various modilications and changes may be made in themanufacture of my improved motorcycle, without departing from the spiritand scope of the invention, and l do not wish to be understood asrcstricting myself except as required by the following claims whenconstrued in the light of the prior art.
